I'm seeing a more modest slowdown with 1.25.0 vs 1.22.0, with the final emcc invocation on my ogv.js library taking ~10s instead of ~4s. This is on a 2012 Retina MacBook Pro running 10.9.5.
However I also notice a *much* larger slowdown the first time I run it after switching to each version, when it says "running sanity checks"... after that first run I get more consistent results (the 10s vs 4s), but it can take an extra 40-100 seconds to do the sanity checks. -- brion vibber (brion @ pobox.com / bvibber @ wikimedia.org) On Thu, Oct 9, 2014 at 4:34 PM, Olivier Chatry <[email protected]> wrote: > Hello, > > Yep I'm seeing the exact same behavior on three macs : one vm, one mini > mac, and my 15" retina with "latest" version.
